The MIS-C patients who were older (P<0.001) had higher median peak values of CRP (P<0.001), IL-6 (P<0.001), ferritin (P<0.001), procalcitonin (P=0.002), left ventricular systolic dysfunction (P<0.001) and lymphopenia (P=0.01) when compared to those without AKI [26]. This evidence concerns the gene CRP and acute kidney injury.
